SPINDLE.

My invention consists in the combination of a downwardly-extending Wire spring with the bolster and step and in the combination of the bolster and step with an oscillating support.

In the accompanying drawings, Figure 1 represents a vertical section of the spindle and the holding-case. Fig. 2 represents a horizontal section taken in the line 2 2 of Fig. l. Fig. 3 represents a vertical section taken in the line 3 3 of Fig. 2. Fig. 4 represents a detail s ide view showing the improved cap for the oil-tube, the said cap being turned to one side for the insertion of oil into the tube. Fig. 5 represents a side view of the combined bolster and step. Fig. 6 represents the top end view of the same. Fig. 7 represents a side view of the oscillating support for the bolster and step. Fig. 8 represents the top end view of the said support.

In the drawings, A represents the spindle, B the whirl, and O the supporting case or holder, held in placeupon the rail D by means of the nut E. Within the cavity a of thesupporting-case O is placed the .oscillating support F for the bolster and step G, the said support being provided with a circular enlargement o, which is supported by the shoulder c of the cavity d, so that the said support F may, if retpuired,` have a slight oscillating movement imparted thereto by the motion of the spindle.- The support F is provided at its upper end with the enlarged cavity d, at the bottom of which is formed the annular shoulder e and having the cavity f, of less diarneter, extending to near the lower end of the said support, the said lower end being provided with a perforation g, which loosely iits the wire spring h, which extends downwardly from the lower end of the step and bolster G, the said step and bolster being provided at its upperend with the circular enlargement e', which loosely fits the cavity a of the supporting-case C and serves to permit an oscillating movement of the said step and bolster, the lower end of which is provided with the downwardly f enlarging portion j, which rests upon the shoulder e in the enlarged cavity d of the support F, the incline of the peripheral surface of the portion j being such as to allow for the required degree of oscillating movement. The step and bolster Gis provided with the groove k, the outer case C being provided with a corresponding pin or spline m, which, entering the groove 7a, serves to prevent the rotation of the bolster and step with the rotating spindle, and suitable grooves n n are made in both the Ybolster and step G and the step-support F for the proper flow of oil.

When the bolster and step G is placed in the cavity of the outer case C, the wire spring Vh will enter the perforation g at the lower end of the step-support, and thus serve to steady the oscillations of the said step--support caused by the rotation of the spindle.

In order to prevent the dust from entering the oil-tube H, I provide a cover I, formed of a tube closed at its upper end o and cut away at the sides p and q, the said tube being indented into the recess r at the side of the oiltube H to form the turning-pivots for the cap.

I claim as my invention- The combination of the spindle, with the holding-case, the oscillatory support for the step and bolster, and the step and bolster provided with 'the downwardlyextending wire spring loosely held in position at the lower end of the oscillatory support, substantially as described.
